# On embedded platforms that don't support shared library targets, CMake implicitly changes shared
# library targets to be static library targets. This results in duplicate definitions of the static
# library targets even though we might not ever build the shared library target, which breaks the
# build. To work around this, we change the output name of the  shared library target so that it
# can't conflict with the static library target.
#
# This is tracked by https://gitlab.kitware.com/cmake/cmake/-/issues/25759.
